<?php
$new_data = array();

$data = array(

    array(
        'name' => 'kunci',
        'value' => '1'
    ),
    array(
        'name' => 'set1',
        'value' => '1'
    ),
    array(
        'name' => 'set2',
        'value' => '2'
    ),
);

foreach ($data as $row) {
    $new_data[] = $row;
}


$new_data = array_filter(arrayToColumn($new_data, 'name', 'value'));

print_r($new_data);

function arrayToColumn($arr = array(), $index = 'name', $value = 'value') {
    //convert list value to column

    /*
    @param $arr = Array()
    @param index like name
    @param value like value

     */

    return array_column($arr, $value, $index);
